Is my DME probably bad?

[San Jose State University]

Hi,
I have some 6 month old DME and I was curious if I can still use it. The bag is not air tight at all, but closed. It was stored at room temp (varied between 70-100 deg F).


I've read about off flavors from using old DME. Is it a risky move to use the stuff?

Taste it.

I'm sure it's fine.

Is it a solid brick?

Taste it.

Leave your address before doing so and if we don't hear back from you in an hour we'll call the paramedics.

I'm sure it'll be fine if it's not congealed or mouldy.

I once made a batch from a 8 year old extract kit. Honestly two weeks after bottling it was pretty good but it didn't age well. At 6 months it was awfull.

That aside, DME will be pretty shelf stable as long as it stays dry. The LME like what I use in the previously mentoned kit would be a bigger problem, but not in a 6-month time frame.

Short answer: Use it

It was probably 6 months old before you bought it.

Hah. You're probably right. Anyways, I'm going to do it all. Taste it, then use it if all is well!!

Off flavors from old extract is usually (I think always) an issue with liquid extract, which does oxygenate / go stale over time. Lots of people suspect that's where "extract twang" comes from. Dry extract doesn't have that issue, which is one reason why it tends to be preferred.
